Abstract

549,015. Oxidizing agents; perphosphates. DU PONT DE NEMOURS & CO., E. I. April 30, 1941, No. 5587. Convention date, May 1, 1940. [Classes 1 (i) and 1 (iii)] [Also in Group IV] Stable dry compositions, for use in the preparation of aqueous oxidizing and bleaching solutions, containing organic peracids or salts, are obtained by mixing a solid inorganic peroxygen compound with a solid organic carboxylic acid anhydride. Specified inorganic peroxygen compounds are sodium perborate monohydrate, peroxides, e.g. of zinc, magnesium or calcium, or a stabilised hydrogen peroxide such as urea hydrogen peroxide, and percarbonates, persulphates or perphosphates of metals, e.g. the perphosphates of the formulae Na 4 P 2 O 7 ,2H 2 O 2 and Na 2 HPO 4 ,H 2 O 2 . Specified anhydrides are those of succinic, maleic, phthalic, benzoic and glutaric acids. The acidity or alkalinity of the solution may be controlled by varying the proportions of the components or by incorporating acid-reacting substances or alkaline-reacting substances such as anhydrous sodium carbonate or tetrasodium pyrophosphate. Soaps, perfumes or flavouring materials may also be present. Examples relate to mixtures of (1) and (2) equimolecular amounts of sodium perborate monohydrate and succinic anhydride; (3), (4), (6) and (7) the same with an addition of various amounts of (3) and (7) tetrasodium pyrophosphate and (4) and (6) sodium carbonate; (5) various molecular proportions of sodium perborate monohydrate and succinic anhydride (8) equimolecular amounts of sodium perborate monohydrate and succinic anhydride with an addition of various amounts of soap; (9) equimolecular amounts of sodium perborate monohydrate and succinic anhydride added to various amounts of water to obtain solutions in which various proportions of the perborate are converted to peracid; (10) equimolecular amounts of sodium perborate monohydrate and glutaric anhydride; (11) and (13) equimolecular amounts of sodium perborate monohydrate and phthalic anhydride; (12) the same with an addition of sodium carbonate. Sodium perphosphates of the above formulae are obtained by treating tetrasodium pyrophosphate and disodium hydrogen orthophosphate respectively with hydrogen peroxide.
